    How to Grow Klondike Blue Ribbon Striped Watermelon

    When to Plant Watermelon Seeds

    If you live in a climate with a short growing season, consider starting your watermelon seeds indoors 4 to 6 weeks before transplanting seedlings into the garden. Sow watermelon seed directly, or set out your transplants 3 to 4 weeks after the last average frost date in spring. Watermelon demands warm temperatures – both soil and air. Transplant or direct sow watermelon seeds only when the average soil and daytime air temps are at least 70F.

    Where to Plant Watermelon Seeds

    Watermelons are heavy feeders and need soil rich in nutrients. They grow best in loose, well-drained, but moisture-retentive soil rich in organic matter. Amend your soil with aged manure, seaweed, and/or compost before planting.

    How to Plant Watermelon Seeds

    Dig a hole 12" deep and 24" wide, fill with compost, manure, and several handfuls of sand. Use the soil that was removed from the hole to create the mound and then sow your seed or transplant there. Sow watermelon seeds 1" deep, planting 4-6 seeds (or transplanting 2-3 of your strongest seedlings) in mounds that stretch 24" across, If direct sowing, wait until seedlings have developed 3-4 true leaves and choose your strongest 2-3 plants by cutting the thinned out seedlings at soil level with scissors. Build mounds 5-10' apart.

    How to Harvest Watermelon

    Stop watering your watermelons about 10-14 days before the fruits are ready to harvest, this will concentrate the plant’s sugars and your watermelon will be sweeter. You may want to place a board under each melon to keep the fruit clean and dry. Watermelons will be ready to harvest after 70-90 days from sowing.

    Other tips (if any): Companion plants are corn, radish, beans, nasturtiums, marigolds and oregano. Bad companions are potatoes as they attract many of the same insects that feed on watermelon plants.

    Avoid growing watermelon where night temperatures dip below 50 F; this will cause fruit to lose flavor. If temperatures exceed 90F for several days, flowers will drop without setting fruit. Watermelons require 70-90 frost-free days to reach harvest and will tolerate no frost. A soaker hose or drip irrigation is the best way to water. If you live in an area where the weather and soil are dry, try planting your watermelon in inverted hills rather than mounds. Regular, even watering will help fruits avoid blossom-end rot which is caused by fluctuation of soil moisture.

This is a trusted and fast shipper of quality seeds. Their selection of non GMO seeds is great. The seeds are planted and starting to break the service. My buddy (86) can hardly waite, I recommed them.
